LOG-TURNER FOR SAW-MILLS.

SPECIFICATION forming part of Letters Patent No. 439,822, dated November4, 1890.

Application filed December 31, 1889. Serial No. 335,480. (No model.)

To all whom it may concern:

Be it known that I, JAMES A. MCLAUGHLIN, a citizen of the United States,residing at Brunswick, in the county of Glynn and State of Georgia, haveinvented certain new-and useful Improvements in Log-Turners for Saw-Mills; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to log-turning apparat-us for saw-mills; and itconsists in certain improvements in the construction of the same, ashereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a log-turningapparatus provided with my improvements. Fig. 2 represents an end viewof the same. Figs. 3 and 4 illustrate the turn-blocks.

A designates the skids, which are placed to extend at right angles fromthe log-carriage B. The ends of the skids which are adjacent to thecarriage are beveled and recessed or cut out to receive the guides C,which are fixed in inclined positions, as shown.

D indicates a series of pusl1ers,each of which is placed between twoguides C, andis provided with a rack bar or teeth a, through which thepusher may be engaged by a pinion or a toothed segment b, which is fixedto a rotative shaft E. A wheel F is carried by each of the pushers,being mounted in the upper end thereof, as shown.

The shaft E is mounted in position parallel with the line of thelog-carriage, and to said shaft is secured a lever J, by means of whichthe shaft may be turned and the pushers raised by the action of thesegments 1), which connect with the teeth Ct.

I indicates a notched quadrant for securing the lever J in position atany desired point.

L indicates a counter-balance secured to the shaft E for assisting inthe operation.

The log G being in position on the headblocks H, as seen in Fig. 2, isusually moved back somewhat before being turned, and the object of theinvention is to effect this lateral movement of the log uniformly andreadily. Such lateral movement is produced by turning the shaft E bymeans of the lever J, whereby the several pushers may be raised, thesegments 19, engaging with the teeth a, and the wheels F, impingingagainst the log as the pushers move upward in their guides. The logbeing thus pushed back, as required, may be turned to the requiredposition by means of a cant-hook M. (Shown in Fig. 2.)

I claim- 1. In a saw-mill, the supporting timbers or skids, which arerecessed and provided with guides, in combination with a series ofpushers placed within said guides and provided with wheels F and teetha, and a rotative shaft provided with fixed toothed segments in positionto connect with the teeth of the pushers,whereby the latter may beraised, substantially as and for the purposes described.

2. The combination, with the recessed skids A, provided with guides O,of the pushers D, provided with teeth a, Wheels F, mounted on saidpushers, rotative shaft E, provided with segments 1?, in position toconnect with the teeth a, and a lever connected with said shaft,substantially as set forth and described.

In testimony whereof I have affixed my sig nature in presence of twowitnesses.

JAMES A. MGLAUGHLIN.
